Floor Elevation is currently available in beta. Workflows, availability, and outputs may change between releases as the feature is refined.

Overview

Floor Elevation turns your FieldPrinter 2 into a tool for measuring slab condition. The FieldPrinter collects elevation data on your slab. The data syncs to Dusty Portal. You get a heatmap and a point report you can download, plus numerical data you can pull into downstream workflows.

This article covers what Floor Elevation does, what you need to run it, and how a job goes from setup to final report.

Who it's for

Floor Elevation fits two kinds of work.

The first is general slab condition work: defining areas for grinding or fill, scoping other remediations, or handing a condition report to the next trade. You want a picture of where the slab is high, where it's low, and by how much. A heatmap answers that.

The second is precision work: compliance checks, building prefab panels to fit existing slab conditions, or equipment baseplate leveling. You need specific numbers you can act on or pass to another system. Numerical exports cover that.

Most jobs land somewhere between those two. Floor Elevation supports both.

What you need

To run Floor Elevation, you need:

• An AT500 Tracker (Hexagon) or AT930 Tracker (Hexagon) for stationing.
• An iPad running Dusty Controller version 2.14 or later.
• Access to the Dusty Portal with the Floor Elevation Beta enabled on your account.

Two Ways to Measure: Points and Areas

You can measure in two ways, and you can combine them on the same layout.

Measurement points. You define specific locations in CAD, and Dusty records an elevation value at each one. Points are the right choice when you need named, precise readings, like equipment footprints, panel corners, or column lines.

Measurement areas. You draw an area in CAD, and Dusty fills it with a grid of readings. Areas are the right choice when you want a general picture of the slab across a region of the floor. Enable measurement areas by switching on Background Measurement.

Setting up the job

Setup for points starts in the Dusty Portal.

1. Add your measurement points as a CSV to a Dusty layout.
2. Set the CSV file to be a measure layer.

Measuring Elevation in the Field

The measure elevation workflow layers onto your normal FieldPrinter workflow. For full step-by-step instructions, see How to Use Floor Elevation (Beta).

1. Complete setup. Level the AT500 Laser Tracker on a stable tripod, open the Setup tab on the iPad, toggle Capture Elevation on, and finish every Setup step until each has a green check mark.
2. Choose how you'll measure.
   • Point Elevation drives the FieldPrinter to specific points from a measure-layer CSV published to your layout. Select the points you want to record and tap Start.
   • Area Elevation drives the FieldPrinter through a rectangular area you draw with the Elevation Area tool. Tap Start and the FieldPrinter covers the area autonomously. Make sure Background Elevation is toggled on during Setup to enable.
3. Watch results on the iPad as readings come in. Use the Heatmap toggle to show or hide the live overlay; data is recorded either way.
4. Fill in gaps. When a queued task completes, check the heatmap for uncovered regions and drive the FieldPrinter through them manually.
5. Restation as many times as the layout needs. Each new station must share at least one control point with a previous station so the cloud can stitch your data together. The iPad warns you when an overlap is missing.

Viewing Results in the Portal

After the FieldPrinter finishes and the iPad finishes uploading, Dusty stitches your stationings together in the cloud. Open the project in Dusty Portal, and you'll see:

A heatmap overlay across measured areas. Color scales to the min and max values, so high spots and low spots read at a glance. The scale auto-adjusts to your data. Outlier readings inside area measurements are filtered automatically, so one bad value doesn't skew the picture.

A point elevation summary. View point measurement data by stationing with different reference points.

Downloads and Reports

• Floor Elevation Heatmap PDF. The layout drawing overlaid with the heatmap and a labeled color scale.
• Floor Elevation CSV. The underlying heatmap data with one row per grid. Pick metric or imperial at download.
• Point Elevation PDF. The layout drawing shows each measurement point's name and elevation called out.
• Point Elevation CSV. Includes point name, X/Y coordinates, and measured Z. Pick metric or imperial at download.

If you work in Autodesk Point Layout, there is a specific CSV file that imports cleanly.

Current Limitations

A few capabilities are not yet supported in the beta.

• Floor Elevation does not print an elevation grid of values directly on the slab as a same-day output. The output is digital first. If you need elevation numbers printed on the floor, take the CSV through your CAD step and print the results on a second pass.
• Floor Elevation does not generate an ACI-format FF/FL report. The CSV gives you the raw data; your team or a third party can format custom reports from there.

Getting Help

If anything is off, reach out to your CSM or open a ticket in Dusty Support. Beta feedback helps us refine the feature.
